Definitions

  • the present invention relates to electrical contacts having tines with uneven edges to provide increased contact normal force and decreased peak stress.
  • a socket contact is designed for mating with a pin contact of an electrical device.
  • a socket contact generally includes a socket that receives the mating pin therein.
  • tines also referred to as contact beams
  • Socket contacts generally have a body with a tubular base and tines which extend from the base at circumferentially spaced-apart locations around the base. The tines are designed for mating engagement with a pin contact which is inserted along an axis between the tines.
  • socket contacts may be made by stamping and forming, drawing, or screw machine methods, but in most cases, material is removed from the body to define the spaced-apart tines.
  • the tines are generally of the same length and designed to grip the pin that is inserted into the socket contact.
  • the present invention relates to socket electrical contacts containing a socket body that includes a base defining a longitudinal axis and tines extending from the base at spaced- apart locations around the circumference of the base.
  • the tines extend from the base in the direction of the axis to define a pin reception zone between the tines.
  • Each tine contains two opposing edges that have different lengths and a blunt tip.
  • the present socket contact design provides improved contact normal force and decreased peak stress when compared to a design without a taper tip (both edges of each tine having the same length).
  • the present invention also relates to methods for making and using the socket electrical contact.
  • Figure 1 shows a three dimensional view of an embodiment of the present invention.
  • Figure 2 shows an outside side view of a tine of the present invention.
  • Figure 3 shows a cut away, inside side view of a tine of the present invention.
  • Figure 4 shows a comparison of the present invention with a socket contact with tines having even edges.
  • the socket contact contains a body 100 which includes a base 102 defining a longitudinal axis and tines 104 extending from the base 102 at spaced-apart locations around the circumference of the base 102.
  • the tines 104 extend from the base 102 in the direction of the axis to define a pin reception zone 106 between the tines 104.
  • the body 100 is generally tubular in shape.
  • the tubular shape may have an elliptical, circular, or parallelogram (such as triangle, square, pentagon, hexagon, octagon, etc.) cross- section.
  • the body 100 of the socket contact may additionally or alternatively include any other shape(s).
  • the socket contact is not limited to being used with a cylindrical mating pin. Rather, the socket and mating zone of the socket contact may be configured to mate with a mating pin that includes any other shape(s) in addition or alternatively to the cylindrical shape.
  • the body 100 extends a length along a central longitudinal axis 107.
  • the body 100 includes a base 102 and tines 104 that extend from the base 102.
  • the socket contacts in accordance with the present invention may contain more than two tines extending from the base at spaced-apart locations around the circumference of the base 102.
  • the socket contact may contain 2, 3, 4, 5, or more tines, although the preferred
  • the embodiment contains two tines.
  • the tines 104 may deflect slightly away from or toward the central axis 107 to allow for cantilever deflection to the tines 104 when they are mated to a pin.
  • the body 100 because it is usually cut and shaped from a single sheet of conductive material, preferably contains a seam 108 in the base 102, which extends in the direction approximately parallel to the central axis 107.
  • Each tine 104 contains an exterior surface 118, a contact surface 120, and two opposing edges 110 and 112.
  • the two opposing edges have different lengths and form a blunt tip 114.
  • the bunt tip is form by a line connecting the short edge 110 to the long edge 112 and is approximately perpendicular to the length axis of the tine 104.
  • Both edges 110 and 112 extend from the base 102 to the tip 114.
  • the long edge 112, as illustrated in Figures 2-3, has a length L; and the short edge 110 has a length 1.
  • the short edge 110 is preferably about 5-12% shorter than the long edge 112, more preferably about 7-10% shorter. In an embodiment, on each tine 104, the short edge 110 is preferably closer to the seam 108 than the long edge 1 12.
  • the slots 122 and 124 formed between the tines also have different lengths. As illustrated in Figures 1-3, the slot 122 formed between the short edges 110 of adjacent tines are shorter than the slot 124 formed between the long edges 112 of adjacent tines. In a preferred embodiment, where the short edge 110 is closer to the seam 108, the slot 122, which is closer to the seam 108, has a shorter length than the slot 124, which is farther away from the seam 108.
  • the body 100 of the socket contact may be fabricated from any material(s) that enable the body 100 to be electrically conductive.
  • the body 100 of the socket contact may be fabricated using any method, process, structure, means, and/or the like, such as, but not limited to, using a cutting process, using a casting process, using a molding process, using a forming process, and/or the like.
  • Cutting processes include, but are not limited to, water cutting, stamping, laser cutting, punching, cutting using a saw, drill bit, plane, mill, and/or other solid cutting tool, and/or the like.
  • Forming processes include, but are not limited to, drawing, bending, and/or the like.
  • approximately flat sheet of material from an approximately flat material, from a rod of material, and/or the like.
  • the body 100 of the socket contact is a cut and formed from a material and then formed to include the shape (e.g., the exemplary tubular shape) of the body 100.
  • various cuts may be made to the material to define the body 14 of the socket contact 10 from the material. Examples of such cuts include cutting an initial shape of the base 102, and/or the tines 104 (e.g., cutting slots to separate adjacent tines from each other and to partially define the shapes of the tines).
  • Other features of the socket contact that may also be cut from the material. Once the material has been cut, the material may be formed to define the finished shapes of the base 102 and the tines 104, and/or other features of the socket contact.
  • the body 100 may be formed to include the exemplary tubular shape shown herein, which may provide the tines 104 with the curved contact surfaces 120. Moreover, for example, the tines 104 may be bent to converge to the central longitudinal axis 107.
  • the finished shape of the body 100 may include the seam 108. Cut and formed contacts may be less expensive to fabricate than machined contacts.
  • the body 100 may be a cut and drawn body that is cut from a material and then drawn to form the finished shape of the body 100.
  • the body 100 of the socket contact is a stamped and formed body that is stamped from a material and then formed to include the finished shape of the body 100 in some embodiments.
  • the socket contacts are cut from a sheet of conductive material, then formed into its three
  • electrical contact e.g. between two electrical devices, is made when the socket contact is mated to a pin contact.
